The Lowdown
Alright folks, Rusty here. Let's be straight with you – it's a tough stretch ahead for the Maine coast, specifically around Kennebunk Beach. The forecast is calling for a long, quiet run with not much to get excited about. We've got a solid 16 days of outlook here, but the truth is, the first two weeks are looking like a total write-off. You'll be staring at flat, weak surf with no real recommendations coming through until we get towards the end of the period. It's a dry spell, plain and simple.
For the first week, from Sunday the 6th right through to Saturday the 12th of September, it's a ghost town. The combined swell energy barely gets into double digits, mostly sitting between 9 and 125 (moderate wave energy at best early on), and we're talking tiny knee-high waves with short periods. The water temperature is sitting at 66°, which is a touch warmer than normal for this time of year, but that's about the only interesting thing happening. The wind is all over the place, but none of it is doing us any favours. The whole week is a bust – you'd be better off waxing your board and staring at it.
Moving into the second week, it doesn't get much better. From Sunday the 13th through to Saturday the 20th, we see a little more pulse in the water, but it's still poor. The swell heights hover around 1.0 ft to 4 ft, with the biggest reading being on Wednesday the 16th afternoon with a 4 ft SSE swell, but the period is a measly 5 seconds – that's pure windswell with no push. The combined energy does hit 103 (moderate) on Monday the 14th morning, but it's accompanied by a moderate cross-onshore breeze that will chop it to bits. There's a few cleaner windows here and there – like the offshore winds on Wednesday the 16th morning and Monday the 21st morning – but the swell just isn't there to back it up.
The only flicker of hope comes right at the tail end. On Monday the 21st of September, we get a morning with a moderate offshore breeze from the NNE at 12 mph and a clean 1 ft swell from the ESE with a period of 9 seconds. The combined energy is 46 (weak), so it's not going to be a world-beater, but the wind is clean and it's the best looking window in the entire 16-day forecast. If you're desperate, that Monday morning session might give you a few clean ankle-biters to yourself, but don't expect anything with any punch.
Honestly, Kennebunk Beach is a sheltered spot and it really needs a proper push of ENE swell to light up. This run is flat and forgettable. If you're a kitesurfer, those choppier days with the moderate breeze might offer something, but for paddle surfing, it's a long wait for very little. The forecasts can always change, but right now, this is a solid two-week gap of nothing.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
